1. 1. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Akila Wajirakumara; [2021]
   Keywords : ;

   Abstract : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.

3. 2. Lean Beam Management for New Radio

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Nawanit Kumar; [2020]
   Keywords : 5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

   Abstract : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. READ MORE

4. 3. Design of Low-Power Wide-Area Networks at Sea

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Michiel Sandra; [2020]
   Keywords : Internet of things; maritime communications; low-power wide-area networks; path loss modeling; Technology and Engineering;

   Abstract : The development of low-power wide-area (LPWA) technologies has opened up for the deployment of wireless networks for new Internet of Things (IoT) applications. One of these is the monitoring of buoys at sea, which tend to detach due to ice, stormy weather or collision with boats, etc. READ MORE

   Abstract : Satellite communication is a widely known method for communicating with remote or disaster-strickenplaces. Sometimes, thecommunication can be a matter of life and death,and it is thus vital that it works well. READ MORE

6. 5. Inter-Satellite Link Antennas : Review and The Near Future

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Arttu Tiainen; [2017]
   Keywords : Satellite; ISL; Communications; Antenna;

   Abstract : The emerging trend in distributed spacecraft systems of using multiple spacecraft which share functions as opposed to independent spacecraft has given opportunities for missions previously infeasible. Inter-satellite link (ISL) communications provide a direct link within the space segment without need of an intermediate ground segment to relay the data. READ MORE
